Short circuit cable support

ABSTRACT

A support for a plurality of cables includes one or more cable separator beams, each with a half-cylindrically-shaped sleeve formed on each end of each beam. A sleeve on one end of each beam is configured to align with a half-cylindrically-shaped end-cap to form an enclosed cylindrical space for passage of one of the plurality of cables. The second half-cylindrically-shaped sleeve on the other end of each beam is configured to align with the corresponding second half-cylindrically-shaped sleeve on the other of the two beams to form another enclosed cylindrical space for passage of another one of the plurality of cables. An elongated flexible fastener has a locking portion on one end thereof that fastens to a tail portion on the other end thereof, configured to surround and fasten the end caps to the beams, and the beams to each other, to secure and support the plurality of cables.

TECHNICAL FIELD

This invention is directed generally to cable supports for a plurality of cables to prevent contact between cables during a short circuit event.

BACKGROUND

A short circuit event is possible with power distribution equipment. At higher short circuit levels, cables must be restrained to keep equipment operational following a short circuit event. The most common method of restraint is called cable lashing. Cable lashing is normally done by wrapping rope around the cables as directed by equipment manufacturers, as the cables enter and terminate in the gear. It must secure like phases of cables together while also attempting to maintain the spacing between opposing phases. This can be labor intensive for many installers of equipment.

What is needed, therefore, is a way to incorporate premade, fixed spaced or expandable bracing supports that are quickly secured to the cables. What is needed is bracing support assemblies that secure like phases of cables together and maintain the spacing between opposing phases.

SUMMARY

A support for a plurality of cables includes one or more cable separator beams, each with a half-cylindrically-shaped sleeve formed on each end of each beam. A sleeve on one end of each beam is configured to align with a half-cylindrically-shaped end-cap to form an enclosed cylindrical space for passage of one of the plurality of cables. The second half-cylindrically-shaped sleeve on the other end of each beam is configured to align with the corresponding second half-cylindrically-shaped sleeve on the other of the two beams to form another enclosed cylindrical space for passage of another one of the plurality of cables. An elongated fastener has a locking portion on one end thereof that fastens to a tail portion on the other end thereof, configured to surround and fasten the end caps to the beams, and the beams to each other, to secure and support the plurality of cables.

In embodiments, an assembly of one or more of the cable separator beams may be configured to support separated positions of two or more of the cables. A single cable separator beam may be used to organize and securely separate two cables, such as two separate groupings of power cables or two separate groupings of communication cables. Two or three cable separator beams may be used to organize and securely separate three or four sets of cable groupings, for example to secure like phases of cables together and maintain the spacing between opposing phases.

DETAILED DESCRIPTION

FIG. 1 is an overall, perspective view of the cable support 100. A cable separator beam 104 maintains separated positions of the cable groupings or bundles of like phases of power cables and maintains the spacing between opposing phases 130A, 130B, and 130C. Example fasteners, such as the elongated tie-wrap flexible fasteners 102 (FIG. 4 ), fasten end-caps 106 to the cable separator beam 104, which secure the cable bundles to the cable support 100. In example embodiments, the elongated tie-wrap flexible fasteners 102 may be formed from an electrically insulating material, for example a flexible plastic, such as polypropylene, or a flexible rope or cable composed of insulating woven, fibers. FIG. 2 shows the half-cylindrically-shaped end-caps 106 and 106′ aligned with the of the cable separator beams 104 and 104′. In embodiments, an assembly of one or more of the cable separator beams may be configured to support separated positions of two or more of the cables. A single cable separator beam may be used to organize and securely separate two cables, such as two separate groupings of power cables or two separate groupings of communication cables. Two or three cable separator beams may be used to organize and securely separate three or four sets of cable groupings, for example to secure like phases of cables together and maintain the spacing between opposing phases.

FIG. 3 shows the half-cylindrically-shaped end-caps 106 and 106′ assembled with the respective half-cylindrically-shaped sleeves 112 and 112′ of the first and second cable separator beams 104 and 104′. FIG. 3A shows the first half-cylindrically-shaped end-cap 106 with mating surfaces 126 a and 126 b that are configured to substantially align with corresponding mating surfaces 122 a and 122 b of the half-cylindrically-shaped sleeve 112 of the first cable separator beam 104.

FIG. 4 shows the example fasteners, such as the elongated tie-wrap flexible fasteners 102, configured to fasten together the two cable separator beams 104 and 104′, and to fasten end-caps 106 and 106′ to the respective cable separator beams 104 and 104′, which secure the cable bundles 130A, 130B, and 130C to the cable support 100. A non-limiting example of a structure for the tie-wrap fastener 102, is shown in U.S. Pat. No. 3,590,442, by Geisinger, for a Bundling Strap, issued Jul. 6, 1971.

FIG. 5 is a perspective view of the cable separator beam 104, showing the first side 118 a and second side 118 b of the first half-cylindrically-shaped sleeve 112 of the first cable separator beam 104. The figure shows respective mating surfaces 122 a and 122 b facing away from the cable separator beam 104 and terminating in a plane perpendicular to the beam axis 114. The cable separator beam 104 has a length along a central beam axis 114 (FIG. 5 ) and respective opposite beam ends 116, 116′.

In example embodiments, the cable support 100 may have different lengths of the cable separator beams 104 and 104′ to accommodate a different levels of anticipated short circuit currents, with larger anticipated currents requiring greater separation between phases. In example embodiments, the cable support 100 may have adjustable length cable separator beams 104 and 104′, using twist to expanded, notches and tabs. In example embodiments, the cable separator beams 104 and 104′ and the end caps 106 may be formed from an electrically insulating material, for example a structural plastic such as polyvinyl chloride (PVC) or acrylonitrile butadiene styrene (ABS). In example embodiments, the end cap 106 may have a threaded insert for attaching to the side of an enclosure or a fixed mounting. In example embodiments, the elongated tie-wrap flexible fasteners 102 may be formed from an electrically insulating material, for example a flexible plastic, such as polypropylene.

A first half-cylindrically-shaped sleeve 112 is formed on the first end 116 of the beam 104 (FIG. 5 ) and a second half-cylindrically-shaped sleeve 112′ is formed on the opposite, second end 116′ of the beam 104 (FIG. 5 ). Each respective half-cylindrically-shaped sleeve 112, 112′ has a first side 118 a, 118 a′ and a second side 118 b, 118 b′ opening outwardly from the beam end 116, 116′, with a cylinder axis 120 perpendicular to the beam axis 114 (FIG. 5 ).

The first side 118 a and second side 118 b of the first half-cylindrically-shaped sleeve 112 have respective mating surfaces 122 a and 122 b facing away from the cable separator beam 104 and terminating in a plane perpendicular to the beam axis 114 (FIG. 5 ).

The first side 118 a′ and the second side 118 b′ of the second half-cylindrically-shaped sleeve 112′ have respective mating surfaces 122 a′ and 122 b′ facing away from the cable separator beam 104 and terminating in a plane perpendicular to the beam axis 114 (FIG. 5 ).

A half-cylindrically-shaped end-cap 106 has a first side 124 a and a second side 124 b opening outwardly (FIG. 3 ). The first side 124 a and the second side 124 b of the half-cylindrically-shaped end-cap 106 have respective mating surfaces 126 a and 126 b that are configured to substantially align with corresponding mating surfaces 122 a and 122 b of the first side 118 a and the second side 118 b of the first half-cylindrically-shaped sleeve 112 (FIG. 3 ).

The first half-cylindrically-shaped sleeve 112 and the half-cylindrically-shaped end-cap 106 form an enclosed cylindrical space 128 (FIG. 3 ) for passage along the cylindrical axis 120 of one or more cables 130A, when the mating surfaces 126 a and 126 b of the half-cylindrically-shaped end-cap 106 substantially align with the corresponding mating surfaces 122 a and 122 b of the first half-cylindrically-shaped sleeve 112.

The elongated tie-wrap flexible fasteners 102 pass through the slot 108 (FIG. 3 ) in the end cap 106. The tie-wrap flexible fasteners 102 are configured to fasten the end cap 106 to the cable separator beam 104 by wrapping around the sleeve 112, lying in the groove 115 (FIG. 5 ), and passing through the slot 110 in the cable separator beam 104, to thereby fasten the end cap 106 to the cable separator beam 104. The tie-wrap flexible fasteners 102 have a locking portion on one end thereof that fastens to a tail portion on the other end thereof. By drawing the tail portion through the locking portion, the tie-wrap flexible fastener 102 tightens around the end cap 106 and the sleeve 112, pulling them together in a mutually aligned and substantially abutting position (FIG. 3 ). The end cap 106′ may be fastened to the cable separator beam 104′ in the same manner. In example embodiments, the cable support 100 may have more than two slots 108 and 110 to add more tie-wrap flexible fasteners 102.

The elongated tie-wrap flexible fasteners 102 are configured to fasten together the two cable separator beams 104 and 104′ in a similar manner. The tie-wrap flexible fasteners 102 pass through the slot 110′ (FIG. 3 ) in the sleeve 112′ of the cable separator beam 104. The tie-wrap flexible fasteners 102 are configured to fasten the sleeve 112′ of the cable separator beam 104 to the sleeve 112 of the cable separator beam 104′ by wrapping around the sleeve 112′, lying in the groove 115 (FIG. 5 ), and passing through the slot 110 in the cable separator beam 104′, to thereby fasten the cable separator beam 104 to the cable separator beam 104′. The tie-wrap flexible fasteners 102 locking portion on one end thereof fastens to the tail portion on the other end thereof. By drawing the tail portion through the locking portion, the tie-wrap flexible fastener 102 tightens around the sleeve 112 and the sleeve 112′, pulling the cable separator beams 104 and 104′ them together in a mutually aligned and substantially abutting position (FIG. 3 ), which secure the cable bundles 130A, 130B, and 130C to the cable support 100.

In example embodiments, the cable support 100 may have alternate connectors to attach the end caps 106 to the cable separator beams 104 and 104′. For example, a hook and latch may be located on one side of the end cap 106 aligned with a wire tie or fastener on the cable separator beams 104 and 104′. As other examples, a slide and lock, snap and lock, or pin and lock may be used as an alternate way to attach the end caps 106 to the cable separator beams 104 and 104′.

FIG. 6A is a perspective view of an alternate embodiment of the end cap 106′, showing a rib 140 with threaded inserts 142 for mounting on a fixed structural support, according to an example embodiment of the disclosure. The rib structure 140 on the half-cylindrically-shaped end-cap 106′, has threaded inserts 142 for mounting the half-cylindrically-shaped end-cap 106′ by means of threaded screws on the fixed structural support. Other types of fastening structures may be used as a substitute for the threaded inserts 142 for mounting on a fixed mounting structure. For example, a sliding dovetail joint may be used to fasten the rib structure 140 to the fixed mounting structure. The vertically oriented rib structure 140 shown in the figure may be formed to be a trapezoidal dove-tail shaped projection in a horizontal cross-section, configured to slide vertically into a vertically oriented slot in a fixed mounting structure, the slot having a corresponding hollow trapezoidal shape in a horizontal cross-section. The sliding dovetails are assembled by sliding the rib into the slot. The sliding dovetail joint enables the half-cylindrically-shaped end-cap 106′ to be fastened to the fixed mounting structure without additional fastening hardware.

FIG. 6B is a top view of an alternate embodiment of the end cap 106′ and the second cable separator beam 104′, showing a hook and latch 144, 146 to fasten the end cap to the beam, and a second latch 148, 150 with a screw fastener 152, 154 to fasten the end cap to the beam, according to an example embodiment of the disclosure. The hook portion 144 on the half-cylindrically-shaped end-cap 106′ fits into the hole 146′ in the latch structure 146 on one of the first and second half-cylindrically-shaped sleeves 112′ of the cable separator beam 104′, which are configured to fasten the half-cylindrically-shaped end-cap 106′ to the one of the first and second half-cylindrically-shaped sleeves 112′ of the cable separator beam 104′.

Another first latch structure 148, 148′ on the half-cylindrically-shaped end-cap 106′ fastens to a second latch structure 150, 150′ on the one of the first and second half-cylindrically-shaped sleeves 112′ of the cable separator beam 104′. A threaded bolt 152 fits through a hole 148′ of the another first latch structure 148 and through a hole 150′ of the second latch structure 150, which is fastened by the threaded nut 154 on the bolt 152. The another first latch structure 148 is fastened to the second latch structure 150 by the bolt 152 and nut 154, which fastens the half-cylindrically-shaped end-cap 106′ to the one of the first and second half-cylindrically-shaped sleeves 112′ of the cable separator beam 104. The bolt 152 and nut 154 may be composed of a metal, such as steel, or alternately may be composed of a structural plastic, such as polyvinyl chloride (PVC) or acrylonitrile butadiene styrene (ABS).

FIG. 6C is a perspective view of an alternate embodiment of the end cap 106′ and the sleeve 112′ portion of the second cable separator beam 104′, showing a pin 166 and lock 160, 162, and 164 to fasten the end cap to the sleeve 112′ portion of the beam, according to an example embodiment of the disclosure. A first lock structure on the half-cylindrically-shaped end-cap comprises a first socket portion 162 extending from the end-cap 106′ perforated with a first axial hole 162′ and a second socket portion 164 extending from the end-cap 106′ perforated with a second axial hole 164′, the first and second axial holes 162′ and 164′ being coaxial with one another. A second lock structure on the one of the first and second half-cylindrically-shaped sleeves 112′ of the cable separator beam comprises a third socket portion 160 extending from the sleeve 112′ portion of the beam perforated with a third axial hole 160′. The first and second lock structures are configured to be fastened together by interlocking the third socket portion 160 together with first and second socket portions 162 and 163 so that the third axial hole 160′ is coaxial with the first and second axial holes 162′ and 164′. In this manner, a straight pin 166, such as a cotter pin, may be passed through the three aligned coaxial holes 160′, 162′ and 164′. The pin 166 passes through each of the first lock structure and the second lock structure, to fasten the half-cylindrically-shaped end-cap 106′ to the one of the first and second half-cylindrically-shaped sleeves 112′ of the cable separator beam 104′.

Another first latch structure 148, 148′ on the half-cylindrically-shaped end-cap 106′ fastens to a another second latch structure 150, 150′ on the one of the first and second half-cylindrically-shaped sleeves 112′ of the cable separator beam 104′ in FIG. 6C. A threaded bolt 152 fits through a hole 148′ of the another first latch structure 148 and through a hole 150′ of the another second latch structure 150, which is fastened by the threaded nut 154 on the bolt 152. The another first latch structure 148 is fastened to the another second latch structure 150 by the bolt 152 and nut 154, which fastens the half-cylindrically-shaped end-cap 106′ to the one of the first and second half-cylindrically-shaped sleeves 112′ of the cable separator beam 104.

In alternate embodiments, the first and second lock structures may be fastened together by more than the three interlocking socket portions 160, 162 and 163 in FIG. 6C. The three interlocking socket portions 160, 162 and 163 may be configured to snap together, so that no pin 166 is required. The first and second lock structures may be fastened together with wire ties.

In alternate embodiments, the first and second lock structures in FIG. 6C may be fastened together by a sliding dovetail joint. The half-cylindrically-shaped end-cap 106′ has a first side 124 a and a second side 124 b opening outwardly (see FIGS. 3, 3A, and 3B). The first side 124 a and the second side 124 b of the half-cylindrically-shaped end-cap 106′ have respective mating surfaces 126 a and 126 b that are configured to substantially align with corresponding mating surfaces 122 a and 122 b of the first side 118 a and the second side 118 b of the first half-cylindrically-shaped sleeve 112′ (see FIGS. 3, 3A, and 3B). The mating surfaces 126 a and 126 b of the half-cylindrically-shaped end-cap 106′ may be formed to be a trapezoidal dove-tail shaped projection configured to slide into a slots in corresponding mating surfaces 122 a and 122 b of the first half-cylindrically-shaped sleeve 112′, the slots having a corresponding hollow trapezoidal shape. The sliding dovetails are assembled by sliding the dove-tail shaped projection of the half-cylindrically-shaped end-cap 106′ into the slots in the corresponding half-cylindrically-shaped sleeve 112′. The sliding dovetail joint enables the half-cylindrically-shaped end-cap 106′ to be fastened to the half-cylindrically-shaped sleeve 112′ without additional fastening hardware.

The resulting apparatus provides support for a plurality of cables and prevents contact between cables during a short circuit event. The apparatus significantly reduces the labor required (and thus the cost) to properly restrain the cables. An additional benefit is the reduced time to commissioning once equipment arrives on site.

Computer program code for carrying out operations for aspects of the present disclosure may be written in any combination of one or more programming languages. Moreover, such computer program code can execute using a single computer system or by multiple computer systems communicating with one another (e.g., using a local area network (LAN), wide area network (WAN), the Internet, etc.). While various features in the preceding are described with reference to flowchart illustrations and/or block diagrams, a person of ordinary skill in the art will understand that each block of the flowchart illustrations and/or block diagrams, as well as combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer logic (e.g., computer program instructions, hardware logic, a combination of the two, etc.). Generally, computer program instructions may be provided to a processor(s) of a general-purpose computer, special-purpose computer, or other programmable data processing apparatus. Moreover, the execution of such computer program instructions using the processor(s) produces a machine that can carry out a function(s) or act(s) specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality and/or operation of possible implementations of various embodiments of the present disclosure. In this regard, each block in the flowchart or block diagrams may represent a module, segment or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.

It is to be understood that the above description is intended to be illustrative, and not restrictive. Many other implementation examples are apparent upon reading and understanding the above description. Although the disclosure describes specific examples, it is recognized that the systems and methods of the disclosure are not limited to the examples described herein but may be practiced with modifications within the scope of the appended claims. Accordingly, the specification and drawings are to be regarded in an illustrative sense rather than a restrictive sense. The scope of the disclosure should, therefore, be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
